TRANSMISSION TUNING 2011-2016-LML
Why do you need TCM Tuning?
- Required for the best possible drive-ability
- TCM Tuning is the best tool to ensure your engine is operating within its preferred rev range
Benefits of TCM tuning over stock include:
- Raised mainline pressure for improved clutch holding capacity and improved transmission life (a DuramaxTuner Exclusive feature)
- Refined shift schedule to take advantage of the wide Duramax Torque curve
- Improved torque converter clutch engagement settings to allow lockup under heavy loads, planting the power to the ground and lower trans temps
- Torque limitations adjusted to allow high RPM fueling in performance applications
- 2nd gear start in 4wd low range (can tap down to first)
- Further adjustments are available for customers with larger than stock turbochargers or significantly oversized tires
TCM Tuning is especially important for trucks with:
- Larger tires (35”+)
- Modified turbo(s)
- Built transmission
- Any modification that impacts operating RPMs
Towing
- Keep your truck in its power band when lugging up a grade
Performance
- Optional 2nd or 3rd Gear Start for competition applications
- Optimize your aftermarket turbocharger performance
